音 (Sound) vs. 声 (Voice) & 耳 (Ear) vs. 聞 (Hear): Japanese Hearing Kanji Guide

In Japanese, if a dog barks or a friend calls your name, that is 声 (koe — a living creature's Voice). If rain hits the roof or a guitar plays music (音楽 ongaku), that is 音 (oto — a non-living Sound)!

English speakers often say 'I heard a strange sound from that room' whether it was a person talking or a chair falling. Japanese draws a strict line between 音 (oto — mechanical or natural sound) and 声 (koe — human, animal, or insect voice)!

Quick Comparison: 音 (Sound) vs. 声 (Voice) vs. 耳 (Ear) vs. 聞 (Listen, Hear)

Compare the four core sound and hearing kanjis in the table below:

5-Second Memory Summary: How to Never Mix Up 音 & 声 & 耳 Again

Did the sound come from vocal cords (a person, bird, dog, or cicada)? Use 声 (koe — Voice). Did it come from an instrument, machine, footsteps, or wind? Use 音 (oto — Sound, as in 音楽 ongaku Music)!
